Q.thornless blackberry turned brown
After transplanting my thornless blackberry, all the leaves and blossoms have turned brown. I have a three year old bush that was in the wrong place in our garden. After moving it about three weeks ago to a sunny spot five feet away, it has lost both blossoms and leaves. What can I do to help it since it must be in shock? Should I prune it back so it can start over?

The most important things you can do are making sure the bush has plenty of water, and cut the branches back 1/3 - 1/2. This article has more information: https://www.gardeningknowhow.com/plant-problems/environmental/learn-how-to-avoid-and-repair-transplant-shock-in-plants.htm
